^^^^^^^^^^^^^^
|

|

This is a simple test of the timer driver (see include/nuttx/timer.h).
|
||||
|
||||
Dependencies:
|
||||
CONFIG_TIMER - The timer driver must be selected
|
||||
|
||||
Example configuration:
|
||||
|
||||
CONFIG_EXAMPLE_TIMER_DEVNAME - This is the name of the timer device that
|
||||
will be tested. Default: "/dev/timer0"
|
||||
CONFIG_EXAMPLE_TIMER_INTERVAL - This is the timer interval in
|
||||
microseconds. Default: 1000000
|
||||
CONFIG_EXAMPLE_TIMER_DELAY - This is the delay between timer samples in
|
||||
microseconds. Default: 10000
|
||||
CONFIG_EXAMPLES_TIMER_APPNAME - This is the name of the built-in
|
||||
application: Default: "timer"
|
||||
CONFIG_EXAMPLES_TIMER_STACKSIZE - This is the stack size allocated when
|
||||
the timer task runs. Default: 2048
|
||||
CONFIG_EXAMPLES_TIMER_PRIORITY - This is the priority of the timer task:
|
||||
Default: 100
|
||||
CONFIG_EXAMPLES_TIMER_PROGNAME - This is the name of the program that
|
||||
will be use when the NSH ELF program is installed. Default: "timer"
